If you've always wanted a digital entry lock but have been uncomfortable with the idea of relying on electricity or batteries to maintain your lock, this mechanical digital entry lock is right for you. The Pushbutton Lockset requires neither wires nor batteries, but it provides fully mechanical pushbutton operation to get you and your family into your home safely. The Pushbutton Lockset has a heavy-duty grade-one latch, which is secure enough for commercial use, but its satin nickel finish will look attractive in any home. Its 11-button keypad offers a total of 2,047 different four- to six-digit codes, so you can rest easily at night, knowing your home or business is safe. Change the code as often as you like. The weatherproof Pushbutton Lockset is vandal-resistant, with stainless steel buttons and clutch protection if the outside handle is forced down. It fits standard door prep with minor modification and can easily be adjusted to a right-hand or left-hand door. This Pushbutton Lockset fits a 70mm latch backset. A 60mm Pushbutton Lockset is also available.
